Resources can be spent most efficiently on proactive activities that focus on stopping the movement of plant seeds and other reproductive parts to new areas. One way that invasive weed seeds and root fragments can be moved is in hay and straw used for animal feed and bedding or in materials used for erosion control. Seeds can also be transferred in animal...

It has become a problem recently in northern California and southern Oregon. Ranchers in Marin County are reporting populations of distaff thistle so dense that they crowd out grasses and native species. The populations appear to spread along an elevation gradient, maybe along cattle trails. Organic growers have tried mowing distaff prior to flowering. This...

Currently, standard cultivation removes weeds from the majority of the bed using sweeps, knives, coulters and blades. Typically a 4-inch wide band is left around the seedline. Weeds in the uncultivated band are typically removed by hand, and the density of weeds that occur there, determines how laborious and costly subsequent hand...

These are organically acceptable products believed to have minimal human health or environmental effects. My first finding was it’s difficult to obtain herbicides with FeHEDTA in Southern California where I am based, but apparently products are easier to find in Northern California. Of the four...
